INVENTOR ma; ATTORNEY Patented Sept. 2, 1930 PATENT OFFICE THOMAS GORE, F BROOKLYN, NEW YORK BEENFORCING ELEMENT FOR THE BEADS 0F AUTOMOBILE SHOES Application filed July 5, 1928. Serial No- 290,547.

This invention relates to reenforcing elements or romets for the beads of automobile shoes, and has for its main object and feature the inexpensive production of a reenforcing element in which the component. members will not chafe or cut and thus weaken each other, nor stretch unduly in use, and one in which all the component parts serve to sustain the stresses to which the element may be sub-' jected.

In the art, as now practiced, it is the custom to form the reenforcing element either by braiding a plurality of round wires into a fiat member or by securinga plurality of parallel round wires together by means of a fine wire that is threaded over and under the parallel wires. The result is that, in both cases, the wires bisect eachother and thus set up considerable internal friction that tends to shorten the life of the element. It has also been found that reenforcing elements so con-' structed will stretch unduly under stresses. A further disadvantage resides in the fact that the reenforcing elements of the prior art are not easily made by machinery but are, as a rule, produced by hand.

I overcome all these difliculties by means of the present invention, three exemplifications of which are disclosed in the accompanying drawings.

In the said drawings:

Fig. 1 is a view in side elevation of a re enforcing element of the character indicated embodying a preferred and concrete form of the invention;

Fig. 2 is a cross-sectional View substantially on the plane of line 2-2 of Fig. 1;

Fig. 3 is a View similar to Fig. 1 showing a' modified form of the invention;

Fig. 4 is a cross-sectional view substantially on the plane of line 4-4 of Flg. 3;

Fig. 5 1s .a view .similar to Fi s. 1 and 3 showing another modified form 0 the invention; and i Fig. 6 is a cross-sectional view substantially on the plane of the line 6-6 of Fig. 5.

. The reenforcin element is flat and consists essentially o a flat core of high-tensile strength, said gore being wrap d with hightensile strength flat' wire or attened wires laid with the convolutions thereof in spaced relation.

The core may consist, as shown in Figs. 1 and 2, of a single flat member 1, or, as shown in Figs. 3 to 6, of a plurality of round wires 1 laid parallel and side by side to form a flatmember. Around this core is wrapped one or more preferably flat or flattened wires laid with the convolutions thereof in spaced relation. In Figs. 1 and 2 the'outer'wire 2 is but slightly flattened, while in Figs. 3 and 4 the outer wire 2 is considerably flattened. In Figs. 5 and 6 the outer wire 2' is not only fiattened but is crimped to conform to the round wires constituting the core, and the wires of the core are spaced.

In all the forms shown the core is of hightensile strength and the outer wire is also preferably of high-tensile strength.

It will now be understood that there can be'but very little chafing or internal friction between the core and outer wires and also that preferably the outer wire, as well as the core, serves to sustain stresses to which the element is subjected. The result is that there is less stretching and therefore a prolongation of life. Also, an element of this type can readily be made by means of machinery thereby bringing down the cost of production.

The element may be used in various ways. It can be cut into lengths and the free ends can be connected by a sleeve, or it canbe coiled several times and simply be held together by the rubber which fills the inter-. stices and which enters between the coils.

I claim:

1-. A flat reenforcing element for the beads of automobile shoes, including a flat core of high-tensile strength, said core wrapped with wire laid with the convolutions thereof in spaced relation, each convolution engaging both edges of the core and extending in'engagement with both faces of the core from edge to edge.

2. A flat reenforcing element for the beads of automobile shoes, including a core consisting of a single flat high-tensile strength member, said core wrapped with wire laid with the convolutions thereof in spaced relation, each convolution engaging both edges of the core and extending in engagement with both faces of the core from edge to edge.

3. A fiat reenforcing element for the beads of automobile shoes, including a fiat core of high-tensile strength, said core Wrapped with high-tensile strength fiat Wire laid With the convolutions thereof in spaced relation, each convolution engaging both edges of the core and extending in engagement With both faces of the core from edge to edge.

4. A flat reenforcing element for the beads of automobile shoes, including a core con sisting of a single flat high-tensile strength member, said core Wrapped with high-tensile strength flat Wire laid with the convolutions thereof in spaced relation, each convolution engaging both edges of the core and eXtend-' 111g in engagement with both faces of the core from edge to edge. 7
